Here's another one from Basic Audio for Fuzz Friday. This is John's take on the Wem Pep Box and adds variable output cap control with the Body control. Should be an easy fit in a 1590B. Here's the schematic for reference. Alternatives to the BC107B would be other lower gain transistors like the BC547B, 2N2222A, 2N3904, 2N4401, 2N5550...
